Silicone Extruded Products
silicone extruded products：Out of silicone products is usually through extrusion machine extrusion silicone molding, extrusion shape silicone is a long strip, tubular can easily cut, but out of the shape of the silica gel has limitations, in the medical device, food machinery widely used.Silica gel as the main raw material processing products, are known as silicone products. Silica gel is a porous substance with different sizes, which are formed by the appropriate dehydration of silica gel. Porous structure with an open, can absorb a lot of material, is a good desiccant, adsorbent and catalyst carrier. The adsorption of silica gel is mainly physical adsorption, which can be regenerated and reused. In the alkali metal silicate (such as sodium silicate solution with acid, acid, then add a certain amount of electrolyte mixing, which generated silicic acid gel; or in the thick of the sodium silicate solution with acid or ammonium salt can also generate silicate gel.
